Samsung has officially announced its fastest Exynos chip to date, a 2GHz dual-core dubbed Exynos 5250.

The new chip will succeed the 4210, used in Samsung’s flagship Galaxy S II phone. Unlike its predecessor, the 5250 is based on the A15 core and it is said to boost CPU performance twofold. It is built using the low-power HKMG 32nm process.

Graphics performance gains are even more impressive. Samsung claims it is four times faster than the old chip and it supports resolutions up to 2560 x 1600, which could come in handy for next generation tablets. Support for stereoscopic 3D is also on board.

The new chips are sampling as we speak, but full scale production will begin in Q2 next year, so we won’t see new Galaxy phones based on it anytime soon.

Samsung has announced its new Exynos chip, the dual-core Exynos 4212 clocked at 1.5GHz. Based on the 32nm HKMG process, the new Exynos 4212 promisses more graphics performance and higher power efficiency.

Following in the footsteps of Samsung's Exynos 4210 that can be found in Galaxy S II models, Samsung has now announced its newest chip based on two Cortex-A9 cores and built on 32nm High-K Metal Gate process technology, the Exynos 4212. Thanks to the new manufacturing process, the new Samsung Exynos 4212 promisses up 50 percent higher 3D graphics performance and up to 30 percent higher power efficiency.

In addition to the new Exynos 4212 chip, Samsung also rolled out a 16-megapixel CMOS sensor for smartphones as well as a 1.2-megapixel one for front-facing cameras that has 720p HD 30fps support.

The Exynos 4212 was said to be sampling in Q4 but recent announcements of 1.5GHz clocked Galaxy S II HD LTE and Galaxy S II LTE are most likely first smartphones with this chip. The CMOS sensors are scheduled to ship from Novemeber.
